[yocto] About the sstate cache

I am working on the project based on the yocto build system, and want to improve the build performance.

There are many packages downloaded from external and won't be changed nearly in the whole project lifecycle. But if doing a clean build these packages will be rebuilt again, I don't know the sstate cache will be used to cache them or not ?

Also does sstate cache only cache the file level or package level ? if only in file level the package making is still not avoided, right ?

Is there document about the details of the sstate cache ?

Any information will be very appreciated.
